New to cgo - unable to include header

Getting Help
1

OS:- windows.
Go version :- 1.11

I have written a program which uses some functions in c header file. I am getting the below error.

Error:
#go build command-line-arguments: invalid flag in #cgo CFLAGS: Files/IBM/SQLLIB

Code:(sql.go)

package main

// #cgo CFLAGS: -I C:/Program Files/IBM/SQLLIB
// #cgo LDFLAGS:  -lsqllib
// #include "sqlcli1.h"
import "C"

import "fmt"

func main() {
	fmt.Println(C.SQL_BLOB)
}

The sqlcli1.h file is LOCATED in C:\Program Files\IBM\SQLLIB\include.
AND my code(sql.go) is LOCATED in C:\Go\programs

How to solve this Error
Thanks in Advance.

specstrings.h file in sqllib/include?

12

I understood that it is not cgo problem. Can u know how to solve it @rot13

14

I checked it, The error was due to specstrings.h file in gcc. I resolved it.

Thanks @rot13

Line 4 means in the code right

Code:-
-lsqllib looks for sqllib folder in the LDFLAGS path.

We have to use it if we have more than one folder in the path
